On the Constitution of Fatty Acids and Fatty Alcohols and Structures of their Branched Chain Materials in Human Skin Lipids Extracted from Soiled Undershirts

Abstract

Fatty acids and fatty alcohols which constitute human skin lipids were investigated by combined GLC-Mass spectrometer using fatty acids (mono basic acids) and fatty alcohols (primary alcohols) occuring in wool fat as standard materials.
Free fatty acids and combined fatty acids derived from try-, di-, mono-glycerides, waxes, and sterolesters consist of straight and branched chain fatty acids, of which constituents are n-C₁₂n-C₁₈ fatty acids, C₁₂, C₁₄, C₁₆, C₁₈ iso fatty acids, C₁₂, C₁₅, C₁₇ anteiso fatty acids and highly branched chain fatty acids.
Free fatty alcohols and combined fatty alcohols derived from waxes consist of straight and branched chain fatty alcohols, which are n-C₁₄n-C₂₅ fatty alcohols, C₁₆, C₁₈, C₂₀, C₂₂, C₂₄ iso fatty alcohols and C₁₅, C₁₇, C₁₉, C₂₁, C₂₃, C₂₅ anteiso fatty alcohols.
